Hi folks,
I'm new to the method this year. I bought myself a Taylor K-2006 and am starting the process. My pool water is nice, but I am starting to get some plaster corrosion.
Setup: Plaster, 24000 gal. Been alternating b/w dichlor and cal-hypo over the years, and I've been using trichlor tabs + dichlor so fa this season.
Levels with the Taylor look like:
TA - 60
pH - < 7.0 (way less .. base demand takes 15 drops to get to 7.4)
CH - 350
CYA - >> 100. (I can only get < 1cm in the test tube before losing the black dot).
I also have some Hach Aquacheck 7 strips. They read approx like this:
TA - 70
pH - 6.4-6.6
CH - 350
CYA - 30-50.
My question is, why such a discrepancy in the CYA readings? Is it a known issue with the strips, the Taylor, or is my extremely low pH affecting one of the tests?
Thanks much.
